Hi guys and girls,

I know it can be done - just have not figured it how :-)
Checked all forums sites - but could not find an answer to my specific query:

Facts:

- Telstra cable connection - modem (box) supplied - only one Ethernet cable can be attached
- Netgear (ADSL) DG834G WiFi
- Know about disabling DCHP on Netgear

but: what IP address etc do I have to put into the Netgear box - and as I have only one Ethernet outlet on the Telstra Motorola box, how to connect it to Netgear to PC (and still be able to use the WiFi function for the laptop)?

Really appreciate all the help I can get - could ask Santa for a new router with WiFi function - but like myself, the Santa's I know are unemployed, too - only creature comfort is my Internet access through Telstra :-)

Cheers for all your workable suggestions

Hello,

-Assign your pc's network adaptor to obtain an ip address auto.
-set netgear to static ipaddress, enter in the ip address and gateway, dns, provided by telstra.
-plug ethernet cable from pc into netgear, use laptop wireless.

Hi Dets00b,

Thanks for that - will try it out as soon as I can.

Would you know if I need to disable the DCHP setting in my Netgear router?

Yes you want to have DHCP enabled, because the computers on your network are expecting an ip address to be assigned to them by your router, so by enabling DHCP you allow your router to do this automatically. Cool

This is easy, I have this setup at home.

Turn the DHCP Turned off in the Netgear, and allow the TelstraClear router to issue DHCP addresses, it will then hand out DHCP addresses with it's gateway instead of the Netgears.

Wireless will work sweet, and you can use the ports in the back of the netgear as well.

ADSL router can't be used with a cable modem. The above advise is nothing but twaddle that simply won't work.

Spyware: ADSL router can't be used with a cable modem. The above advise is nothing but twaddle that simply won't work.

Here's how it works, your Cable modem works as per normal, connecting to the internet, doing DHCP and plugging into your network, and the ADSL router.

You then disable DHCP on the ADSL router, but Leave wireless enabled.
You then connect to the wireless on the ADSL router, and your laptop goes off on the network and gets a DHCP address from the cable modem, with the correct gateway, DNS servers etc and allows you to be on the internet over wireless... through your cable modem.
I have this exact setup working at a client, and a slightly different config with two ADSL modems at home (instead of a cable and ADSL modem.)
Just because you arn't smart enough to make it work doesn't make it twaddle mate.

Yes this will and does work, no twaddle involved. However only one PC can be connected as only one IP is available, to use more than one you will need a NAT router, which in this situation is not available to you, essentially you run it as a simple wireless AP. As a point of interest many domestic ADSL modems can be reconfigured (if the have a CLI interface) to have the WAN port directed away from the DSL modem and to one of the LAN ports, there are several threads on Whirlpool on this, just a matter or changing the vlan tables.

Hi guys, I am really impressed about all the replies - had a first go at it but no success (yet) --> was called away in the middle of it and hope to finish soon.

Cyril, one quick question - when you say I can only use one PC (as only one IP address), does that mean only one cabled PC - and can I still connect wireless to one or more laptops (or does the laptop - even if wireless - take the IP address over?)

Again, thanks a lot for all the feedback - learned heaps already :-) - and if I can't get it to work after all that expert advice, I will need to check with Santa for a "proper" wifi router for cable modems Cool

Hi, you can only have one IP address, therefore one PC on a TCL connection, the modem is simply a layer2 bridge, and thats all they offer, regarless of wifi or not. If you want more than one PC on the system then get yourself a proper NAT router. In the last few weeks I have installed numerous Dlink DIR-300 routers a brand I normally would not push on anyone, but it seems these things work very well and have good WAN<>LAN throughput and at $80 are a no brainer. Only reason I have used them is for the Tomizone aspect, but in using them both on ADSL and TCL cable connections I have found them to work very well, but thats based on normal web browsing, if you start pushing torrents through them as with most low end routers expect them to fold.

Thanks, Cyril - this helped a lot!

Also great you included the link for the router - was looking for a good supplier for PC stuff in NZ (just recently moved back to New Zealand).

Have a great holiday - and to all other in Geekzone of course, too!

Cool
